I just went backpacking in the smokies. The bag was able to fit in the sleeping bag compartment of my 40L north face pack without issue. It's sack is fleece lined which was nice and comfy stuffed with my extra clothes as a pillow. I'm usually cold natured but found myself very hot after bundling up for bed. I was plenty warm sleeping in leggings and a L/S thermal and even had to remove my socks. I used it unzipped in the 40-45 degree night. I don't have much to compare it to however as a beginner backpacker but it was perfect for the price (I did buy item on sale.) I had plenty of room with the regular and I am an average sized female at 5'5".

I like that the bottom of the sleeping bag is like a pocket, in that the zipper does not zip all the way down past the feet. Some people may not like that if they like sleeping with their feet out. So far, I've only used this at 50F night temp and I was very warm and didn't need to zip it all the way. The fabric is very soft and pillowy and there was plenty of room (I am female, 5'9). Packing it back up was pretty easy compared to others I have used.

I was time pressed to get a new sleeping bag and the store did not have the one I wanted in stock. They said it could be delivered in 2 days to my house for free. I was skeptical but they delivered on time and I am impressed

It has some good features as an internal pocket, and the adjustable hood. It is also very comfortable.

There are two bad things about it. The first one is that it packs a little too large, which makes it impossible to fit in a rucksack's sleeping bag compartment. And the second thing is that I felt cold on a temperature about 32F, so I am not sure how well it would perform at 20F.
